1999 solar eclipse corona in polarized white light. Preliminary Results

Abstract

This paper deals with the preliminary results of August 11, 1999 white-light polarization observations carried out in Turkey (Turhal). The corona was photographed in three positions of the polaroid differing by 60°, and the twelve pictures were obtained. All the films are analyzed by means of image processing technique. After coronal holes are identified in Solar Geophysical Data and from the corona observations, distributions of polarization degree and brightness in these holes are obtained and the results are discussed.
